Moreover you shall say unto them, Thus says the LORD; Shall they fall, and not rise? shall he turn away, and not return?
All Commentaries on Jeremiah 8:4 Go To Jeremiah 8
Cyril of Alexandria
AD 444
It is worth our while observing, in what way his sin was forgiven, and how he put away his fault. The event may prove of no slight benefit to us. He did not then defer his repentance. Nor was he careless about it, for as rapid as was his decent into sin, so quick were his tears because of it. Nor did he merely weep, but he wept bitterly. As one who had fallen, so bravely did he spring up again. He knew that the merciful God somewhere says by one of the prophets, “Shall not he that falls arise? And he that backslides, shall he not return?” In returning, therefore, he did not miss the mark, for he continued to be what he had been before, a true disciple.
